Hi Connie.
If a bull from the U.S. is brought in by a semen company like Genex, or ABS, then the parentage has been checked, bulls used for A.I. require parentage verification to the fullest extent possible.
For AI bulls, Pg 42 of the Handbook, Section 1 (a) says:
"All bulls from which semen is collected for use in A.I. must have parentage verified by DNA typing to the fullest extent possible"
For an American registered walking bull, bought by a breeder, parentage verification hasn't been a requirement in the past. The Board recently changed the rule, after the October Board meeting, so we are requiring sire verification on every breeding bull we register calves to. Up until the recent Board meeting, the rule just stated that a bull needed DNA on file at CAA.
The DNA policy on page 53 of the handbook says:
"Sire policy – all sires used for breeding must have a DNA profile on record with CAA before their off-spring can be registered."
This wording will be changed the next time the Handbook is printed, but we are currently following the rule whereby we check for sire verification on all bulls used for breeding. This can be found on our web-site, under the Board of Directors page, summary from October board meeting.
Sire Verification
Two recent parentage errors that followed American sires used in Canada encouraged the Board to standardize our requirements. An Amendment was passed requiring that "all imported sires be sire verified before progeny can be registered in order to be consistent with Canadian standards."
We are bound to find a few errors relating to past entries, unfortunately.
Let me know if you have any questions, or if you have specific animals you want me to look up.
